What’s an early experience that ignites a passion for science? Three scientists working to inspire the next generation remember what first excited them.“I used to pan for gold when I was little,” said Damon Tighe, today a genomics researcher and science educator. “It was my first experience with separation techniques. It’s still what I think about when I separate proteins or DNA.” Horacio Enriquez, now an engineer and materials manager, remembered when, as a high school student in the 1980s, he first saw a computer assisted drawing on a screen. “We didn’t have a computer. We couldn’t afford a computer. So seeing the CAD image touched on that and also made the connection for me with how products, electronics are designed.” And Stacey Abidayo, now a chemist, thought back to when her parents, both scientists, gave her a microscope when she was little, then caught insects on their lawn to look at with her. “I remember them showing me the wings of a fly, all the different venation,” she recalled.
With such formative experiences in mind, Tighe, Enriquez, and Abidayo are all enabling students today to have their own powerful science experience: getting to see their own DNA. These working scientists have been participating as early volunteers in the Bio-Rad Science Ambassador program. Launched in a pilot phase in August 2012 and now fully live throughout the U.S. and Canada, this initiative helps connect active researchers with local teachers, getting the scientist into the classroom with a free Genes in a Bottle kit for an exciting and age-appropriate lab. Using the kit, up to 36 students at a time learn about DNA by extracting and precipitating their own, then keeping it for all time in a specially designed necklace. Having already served more than 1,000 students across the U.S., the Science Ambassador program appears to be taking off, with new researcher-classroom connections happening every day. It’s a simple formula — any working scientist or classroom teacher can participate, regardless of professional affiliation. The scientist signs up to volunteer through a website that enables area teachers to reach out to her or him. Once a teacher and scientist connect, the researcher goes to the school and performs the DNA extraction experiment with the kids. The Genes in a Bottle kit is suitable for a wide range of students, from grades three to twelve, and the experience it provides — watching one’s own DNA materialize before one’s eyes — produces a near-universal “wow!” Of course, as Enriquez found, even having a ready-made lesson doesn’t remove the challenges of going into the classroom. “You can prep as much as you want going into it, but it’s all about the dynamics of the classroom, if the kids are going to be receptive to you, or if it’s going to be a total disaster,” Enriquez said, thinking back to his first day as an ambassador at a Sacramento middle school.
“It’s nerve-wracking,” Abidayo admitted regarding her first outing, at an elementary school in Hercules, CA. “In the corporate world, you have a certain demeanor, but children are so honest, so brutal.” Enriquez and Abidayo overcame their initial fears (Tighe, a former high school science teacher, didn’t have the same level of trepidation), and each has now done several Science Ambassador sessions for different classrooms, guiding students through the process of harvesting cells from their own cheeks, lysing the cells, precipitating the DNA, and then preserving their genetic material in a clear amulet. “The principal did the extraction with us,” said Abidayo of her first session. “It showed that the excitement people get transcends age. The fifth graders thought it was the coolest thing ever, and here the principal is, ‘look at my own DNA! It’s kind of brown from the coffee I drank…awesome!’” (A student in that group also produced purple DNA material from drinking grape soda before class.) While most students are aware of DNA and its importance, getting to see their own genetic material makes a new — and slightly shocking — connection for them. “Most of the students are used to seeing DNA as the double helix,” noted Damon Tighe. “Their immediate response is, ‘That’s my DNA? That wad of snot floating in there is my DNA?’ You’re bridging the conceptual world to the real world for them, which doesn’t happen a lot in academia. You never get to see or touch anything, so usually the first response is the visceral, ‘oh, that’s what my DNA looks like.’” Making such a big, personal connection opens the door to further conversations outside the classroom. “A teacher I was working with last week told me that the students would leave her room with those DNA necklaces on, and by lunch, the other teachers are asking, ‘what’s happening in your classroom today?’” Tighe recalled. “Then the student brings the necklace home, and causes a conversation there. It’s really nice that this very simple activity suddenly pulls together an entire community.”
You’re bridging the conceptual world to the real world for them, which doesn’t happen a lot in academia. You never get to see or touch anything, so usually the first response is the visceral, ‘oh, that’s what my DNA looks like.’For now, though, the effects of the Science Ambassador program are most visible in individual students it reaches. “This one girl who did the DNA extraction, she’s seven,” Abidayo said. “I know her parents, so I still see her from time to time, and to this day she’ll come up to me and say, ‘Do you know what DNA is? I know what DNA is.’” Scientists in all 50 U.S. states and Canada can now participate in the program. To learn more, visit the Science Ambassador program website at www.bio-rad.com/scienceambassadors.
